在有机光电子学中，聚合物发光器件（PLED）被认为是一类重要的器件，其可以由于半导体聚合物中发生的辐射衰减而将电转换为光。近年来，人们一直致力于开发高效的白色发光PLED，因为它们在下一代平板显示器和固态照明光源中具有潜在的应用。在本教程中，我们将总结白色发光聚合物和器件的进展，直到2009年4月出版的主要著名机构在这一领域。特别关注的是最近的进展，在实现高效率的器件通过掺杂到聚合物主体的电致磷光客体和其他方法。此外，我们将总结新的策略，以实现白色发射，同时荧光和/或磷光发射从一个单一的聚合物，其中单线态和/或三重态生色团被纳入到聚合物侧链或主链通过共价键。
Within organic optoelectronics, polymer light-emitting devices (PLEDs) are regarded as an important class of devices which can convert electricity into light as a result of radiative decay taking place in semiconducting polymers. Recently, much effort has been devoted to developing efficient white emitting PLEDs for their potential applications in next-generation flat-panel displays and solid-state lighting sources. In this tutorial review, we will summarize the advances in white emitting polymers and devices published up till April 2009 by major prestigious institutions in this field. Special attention is paid to the recent progress in highly efficient devices realized by doping an electrophosphorescent guest into a polymer host and other approaches. Also we will summarize the new strategies to realize white emission with simultaneous fluorescent and/or phosphorescent emission from a single polymer in which singlet and/or triplet chromophores are incorporated into the polymer side or main chain through a covalent bond.
